Add check endpoint which can be used with nginx' auth_request function (#266)
* Add check endpoint which can be used with nginx' auth_request function

* feat(cmd): allow configuring redirect domains

* test: add test environment for the nginx_auth PR

This is a full local setup of the nginx_auth PR including HTTPS so that
it's easier to validate in isolation.

This requires an install of k3s (https://k3s.io) with traefik set to
listen on localhost. This will be amended in the future but for now this
works enough to ship it.

* docs(admin): rewrite subrequest auth docs, make generic

* docs(install): document REDIRECT_DOMAINS flag

Signed-off-by: Xe Iaso <me@xeiaso.net>

* feat(lib): clamp redirects to the same HTTP host

Only if REDIRECT_DOMAINS is not set.

<summary>Why am I seeing this?</summary>
<p>
You are seeing this because the administrator of this website has set up <a
href="https://github.com/TecharoHQ/anubis"
>Anubis</a> to protect the server against the scourge of
<a href="https://thelibre.news/foss-infrastructure-is-under-attack-by-ai-companies/">
AI companies
aggressively scraping websites
</a>. This can and does cause downtime for the websites, which makes their
resources inaccessible for everyone.
</p>
<p>
Anubis is a compromise. Anubis uses a <a href="https://anubis.techaro.lol/docs/design/why-proof-of-work">Proof-of-Work</a>
scheme in the vein of <a href="https://en.wikipedia.org/wiki/Hashcash">Hashcash</a>, a proposed
proof-of-work scheme for reducing email spam. The idea is that at individual scales the additional load is
ignorable, but at mass scraper levels it adds up and makes scraping much more expensive.
</p>
<p>
Ultimately, this is a hack whose real purpose is to give a "good enough" placeholder solution so that more
time can be spent on fingerprinting and identifying headless browsers (EG: via how they do font rendering)
so that the challenge proof of work page doesn't need to be presented to users that are much more likely to
be legitimate.
</p>
<p>
Please note that Anubis requires the use of modern JavaScript features that plugins like <a
href="https://jshelter.org/"
>JShelter</a> will disable. Please disable JShelter or other such
plugins for this domain.
</p>
</details>
<noscript>
<p>
Sadly, you must enable JavaScript to get past this challenge. This is required because AI companies have
changed
the social contract around how website hosting works. A no-JS solution is a work-in-progress.
